Question about video quality...?

Um... I download two anime about 24 minutes and 24 seconds. The anime's are Clannad which goes around 24 episodes and La Corda d'Oro about 26 episodes. Both, when combined, gives a memory consumption about 8.5GB [one episode is about 165-170MB]. The original video resolution is 704x400 and a bitrate of 714kbps and it's in .avi format. I'm planning to reduce the file size by converting or whatever process I should do just to make the memory consumption lesser! So... guys, what should I do to make it smaller?

PS: I don't want to change the video size. Changing the bitrate and format would do but PLEASE, don't answer: %26quot;you should lessen the bitrate.%26quot; If you're gonna answer this, specify how much bitrate should I put like: from 714 to 700... etc.

One more thing, does changing .avi to .wmv can make it smaller? If not, what type?



Thanks...^^Question about video quality...?
MPEG will make it a much smaller file even if you keep the same screen size. Adjusting bit rate is something you have to experiment with to get the quality and file size YOU want. No one can give you an exact number. If you want to go that route, cut it down to 1/4 the current rate. If that's too much, now you know your lower limit. Go back to 1/2 the bit rate. If you had an app like Sorenson Squeeze, you could experiment with that in less than 5 minutes to figure out the proper settings.Question about video quality...?
714 is not a great bit rat anyway and if there is a lot of fast action I would want it to be higher. AVI is not a format its a container!, the important thing is the codec used to compress it. if you keep the original size and reduce the bit rate the video is going to deteriorate rapidly.



The more you try to reduce the video size the more the quality will reduce, fact of life, unless you change the picture size which you don't want to do. What do you want to do with the videos? that has a big influence on the file type.



Its going to be hit and miss, but you need to tweak the video as you convert it, but as you dont give a lot of information there is not much else we can do

714 kbps is about as compressed as video can get. for comparison, miniDV is 25000 kbps. the slowest rate i have seen on camcorders is about 4000 kbps. the only hope of going smaller is MPEG1 at 360x240 and reduce frame rate to 6 fps. AVI is audio and video, at these super compression rates, audio becomes a significant contributor to the data rate.
